Abnormal Communication with Steering Wheel Control Module
There is a communication problem with the steering wheel controls.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The car's computer can't talk to the steering wheel controls because of a wiring issue or a problem with the controls themselves.
What the computer is actually seeing
The vehicle’s computer sees that signals from the steering wheel control module are missing or inconsistent, indicating a communication error.
What a healthy reading looks like
Check for vehicle voltage supply of 12V at the steering wheel control module, and ensure data transmission signals are present at the expected levels during operation.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the wiring and connectors at the steering wheel control module for damage or corrosion. Repair if necessary. -> If repaired, clear the code and retest.
- 22. Measure voltage at the steering wheel control module harness. It should read close to 12V with the ignition on. -> If voltage is low or absent, trace back to the power source.
- 33. Use a scan tool to check for any additional codes related to the steering wheel controls. -> If other codes exist, address them first before proceeding.
- 44. Replace the steering wheel control module if wiring is good and codes persist after clearing. -> If replacing, verify that new unit is programmed correctly.
Common causes
- Damaged wiring to the steering wheel control module
- Faulty or disconnected steering wheel control module
- Corrosion or dirt in the connector
- Issues with the steering angle sensor
